How to contact support
Registered customers should contact Mon through in-app support. The support desk is designed for account questions, virtual card questions, transaction questions, evidence upload, complaints, recovery cases, and security issues.
Mon does not use a public website contact form for customer account support because customer authentication, evidence handling, and case audit history must remain inside the app.
Response expectations
Mon aims to provide an initial response within 1 hour. Some cases may require issuer, identity, payment, compliance, or technical review. Where extra review is required, the first response may take up to 24 hours.
Urgent security issues
If you suspect unauthorized access, a lost device, card compromise, fraud, or an incorrect transaction, open an in-app support case as soon as possible and use available in-app controls to freeze or block card access where available.
Evidence
Support may ask for screenshots, receipts, merchant communication, beneficiary details, identity recheck information, device information, or other evidence. Do not send full card credentials, passwords, PINs, authenticator codes, or one-time passcodes.
